Answer / gaurav
It should be 13
(5+3+2+2+1)- please see descriptions.
25= 5 5 5 5 5 - 5 races
select top three from each as it may possible three of any
group are best three.
3+3+3+3+3=15
now
15= 5 5 5 - 3 races
again select top three from each
3+3+3=9
9= 5 4 - 2 races
6= 5 1 - 2 races
4= 4 - 1 race
that's y (5+3+2+2+1)

Answer / saurabh
13 races in total.
It might also happen that all best 3 horses are running in
one of the 5 races all together. Therefore we will be
selecting top 3 for every race.
After 5 races-->we will have top 15 horses
+ After 3 races-->we will have top 9 horses
+ after 2 races--> we will have top 6 horses
+ after 2 races--> we will have top 4 horses
+ after 1 race--> top 3 horses
Total races = 13
